This resets the default sort function to be in the 'unsorted' state.  That
is, it is in the same order as the child model. It will re-sort the model
to be in the same order as the child model only if the <a class="link" href="gtk3-GtkTreeModelSort.html#GtkTreeModelSort" title="struct GtkTreeModelSort"><span class="type">GtkTreeModelSort</span></a>
is in 'unsorted' state.

This function should almost never be called.  It clears the <em class="parameter"><code>tree_model_sort</code></em>
of any cached iterators that haven't been reffed with
<a class="link" href="gtk3-GtkTreeModel.html#gtk-tree-model-ref-node" title="gtk_tree_model_ref_node ()"><code class="function">gtk_tree_model_ref_node()</code></a>.  This might be useful if the child model being
sorted is static (and doesn't change often) and there has been a lot of
unreffed access to nodes.  As a side effect of this function, all unreffed
iters will be invalid.
